Seismic Performance of Reinforced Concrete Corner Beam-Column Joint Subjected To Bi-Directional Lateral Cyclic Loading


Abstract eng:
Seismic performance of a corner beam-column joint in reinforced concrete frames was studied by testing two threedimensional corner beam-column subassemblage specimens without slabs under constant column axial load and bidirectional lateral cyclic load reversals. A column-to-beam flexural strength ratio was varied from 1.4 to 2.3 by changing the magnitude of column axial load. Although a sufficient margin to prevent shear failure was provided to a beam-column joint in the test, subassemblage specimens failed in joint hinging after beam and column longitudinal bars and joint hoops yielded. The ultimate joint hinging capacity of a corner joint under bi-directional lateral loading was enhanced by column compressive axial load, and can be estimated based on the new mechanism proposed by Kusuhara and Shiohara.
